STRIPING DEVICE Filed March 8, 1955 IN VEN TOR.

ATTORNEY.

Patented July 13, 1937 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to striping devices and more particularly to a typeof device that is used for marking athletic fields for games such asfootball, tennis, baseball and the like, or for marking 5 traffic lineson highways or roads.

The object of my invention is to provide a means for conveying the limeor other material used and dispensing it in stripe form on the groundleaving a clear, distinct mark. Provisions having been made in theconstruction of the device to enable it to be turned in either directionat right angle to a straight line.

Another object of the invention is to provide a means that willaccomplish the above and permit controlling the amount of markingmaterial applied by a manual adjustment made by the operator.

Still another object of the invention is to provide a device of thecharacter described that will, during the operation of applying the markor stripe on the ground, keep the material used for marking agitated,thereby preventing the congealing or setting of the material, thusallowing an even mixture to be applied at all times.

The invention is fully described in the following specification of whichthe accompanying drawing is a part and in which the separate parts of myimprovements are designated by suitable reference characters in each ofthe several views, and in which- Fig. 1 shows a fragmentary crosssectional side view of the entire device, and

Fig. 2 shows a fragmentary cross sectional front view of the device.

Referring now to the drawing in detail wherein like characters ofreference denote corresponding parts, the reference character Ill,denotes a receptacle in which the marking material in liquid form isplaced. This receptacle is provided with a cover I to keep the liquidmaterial from splashing out of the top when the device is propelled overthe ground.

The shaft I2, supports the agitator l3, consisting of a plurality ofhorizontally disposed arms joined at the ends by arms placed at rightangle with the horizontal arms. This agitating assembly is supported bybearings 39 and 39A, respectively. The bearings 39, being equipped witha stufilng nut 40, holding a packing in place to prevent the liquid fromescaping from the receptacle l0, through the hearing.

There is a driven sprocket l4, mounted on the shaft l2, and a chain l5,shown over the sprocket I4, is actuated by a drive sprocket l6, mountedon the horizontal axle shaft H, which supports the device and engagesthe wheels 34, at both ends. Theaxle shaft I1, is mounted in adjustablebearings I, having adjustment screws 33, to take'up the slack of thedrive chain IS.

The liquid material is dispensed from the re- 5 ceptacle l0, through thevalve I 9, equipped with a lever handle 20, mounted on the valve stem2|. This valve l9, when opened allows the liquid marking material toflow into a pivotally mounted spout 22, hinged at 23, on the brackets35, and kept in position to contact the ground at all times by thetension exerted by the resilient member 3|.

The entire unit is mounted on a frame consisting of a rearwardlydisposed bracket 21, and the side supports 28 and 28A, respectively,which terminate into handles 32, at the top. There are rotatable mountedcaster wheels 25, supported by yokes 24, and fastened at 26, on theframe. These casters swivel in the mounting 2B, and allow for turningthe entire device at right angles while being operated on the field.

The flexible cable shown at 29, fastened at one end to a hand operatedlever at 30, engaging notches or grooves 38, in one of the handles,actuate the dispensing valve |9, allowing for adjustment in the controlof the flow of liquid through the valve i9, out of the receptacle Ill.

The device is further provided with an indicating medium 36, pivotallymounted at 31, providing a guide for the operator. This indicatingmedium I6, may be suspended on a chain or cable, not shown, when in adownward position of! the ground so as not to interfere with theoperation of the unit.

In operation the liquid marking material such as lime or paint is placedinto the receptacle l0, and the cover II, is closed to preventsplashing, the entire device is mounted on the wheels 34, and thecasters 2!, these will permit its being propelled over the ground by theoperator who 40 pushes on the handles 32. The indicating medium 38, islet down to a position an inch or two off the ground, as shown by dottedlines in Fig. 1. As the device is propelled along the ground thepivotally mounted spout 22, has its lower edge contacting the ground andthe operator opens the valve l9, by means of the lever 30, insertingthis lever into one of the plurality of slots 38, provided on the handle32. These slots will hold the lever 30, which is attached to the 50flexible cable 29, in a fixed position and the flexible cable 29,actuating the valve lever 2|], on the valve stem 2|, opens or closes thevalve Hi.

In this manner a manually governed amount of liquid marking material isdispensed through the 5 valve l9, to the spout 22, which lays it ontothe ground while the device is being propelled over the surface of thefield.

While the device is in motion the drive sprockets l6, revolves theagitator l3, inside of the receptacle II], by means of the drive chainl5, over the driven sprocket M, which is fastened to the shaft l2, ofthe agitator I3. This will keep the marking material mixed, preventing{the heavy particles from settling to the bottom of the receptacle. Theindicating medium is used merely as an index to follow a line or guideon the ground for the convenience and efliciency of the operator.

The invention is susceptibleto various changes in its form and minordetails of construction, and the right is herein reserved to make suchchanges as properly fall within the scope of the appended claim.

Having thus described my invention, what I claim and desire to secure byLetters Patent in the United States, is:

In a device of the character described the combination of a wheeledframe, a receptacle mounted on said frame, a shaft horizontally mountedin said receptacle, said shaft journaled in bearings mounted on the wallof said receptacle, agitating means mounted on said shaft within saidreceptacle in close proximity to the bottom thereof, a sprocket mountedto a depending end of said shaft, a sprocket on the axle of said wheelframe, a chain engaging the sprocket on the axle and agitating shaftrendering said agitating operations when said axle is revolving, anoutlet valve on the bottom of said receptacle, a spout pivotallysupported from the bottom of said receptacle and underlying said outletvalve, a resilient member for depressing the rearwardly directeddischarge end of said spout toward the surface to be striped, an indexcontrol for opening said outlet valve, and a sight guide memberprojecting forward from said frame to guide the operation for accuracyin the operation of the device.
